"To aZZ *wilma it may concern:

Be it known thatv I, OTTO' H. HUNT, a citizen of theV United States, residing at Walla Walla, inthe county of Walla Talla andfStateof Washington, have invented certain new and useful Improvements'in' Signal Devices for"Motor-Vehic1es, of which the ,following is a specification.

v- Ijhis4 invention relates to signal devices einiloyed in connection `Withmotor vehicles, an "designed t 'indicate and give timely Ivvarningto" drivers ofrotlier vehicles, as Well as tofp'edestrians, traiiic officers, etc-at 1ntersections of streets or other places, .of conteiiiplated changes in" the course or direc tion of the car.

The inventionhas for its object to pro# vide a simple and efficient device oi' the character statedf and one which is so arranged that 1t will warn vehicles or pedestrians ap K proaching" from the front, the rear or either side', the device being specially` valuable at companying drawing forming a part ot' this specification. g

Y as

street. intersections for positively indicating to any approaching car the intendedV directlon or course of the car carrying the signal.`

The object stated is attained b v means of a novel 'combination and arrangement of iper-ts tobe Hereinafter .described and claimed, and in order that the saine may be. better'. unc'lerstod, reference is had to thal alc `In* the drawing, Figurel aplan vievv showin ithe application ofthe invention; Fig. 21s a front elevation of the signal. de-n lvice;- Fig. 3v is a cross-section on tleline 3-3 of Fig. Land Figcl. is4 an4 elevation" showing` a slightly modified torniof clamp.

Referring s;nicifically` to the drawing, 5 denotes an. indicator arm carrying at its outer 'enda "suitable illuminating device suchl as "an ordinary incandescent electric lamp 6. `The arm is an elongated, fiat sheet V` metal. plate, with its longitudinal edities'v rolled to obtain the necessary rigidity, and itis carried fbya shank 7 having a flattened outer end `portion 8 in the shape-of an arrow, the same beinggriveted Vor otherwise fastened to ythe iront'face of the' arrn." An arrow 9jma`3y also be applied to the rear 'Lface ofthe arm,

The signal arm hereinbeforedescribed is supported bythe frame of the Windshield of the tar, and it is mountedso thatit may i be s wung'in a horizontal plane' to oint .straight ahead, oridewisefito the ris t 01 left of the car. Y l i i l I means are provided y,forlthis purpose c. v

A fragment ofthe Windshield'frame. is shown' at 14; and tothis part is" attached a clamping member composed ofi tWOOPPOsite drawn together by bolts 17t0 'grip said part 14. The inner faces ofthe jaws lawsuit ably shaped to correspondtothe cross-see The following supporting y jaws '15: and 16, respectively, which are' tional contour of the part 1 4. usaid part isrectangular, the jaws mayV be correspondingly shaped as shownY inl Figi 4, thejaws bemghere denoted by `the reference chars@ ters 15 and 16?. 4 i. i

The jaw member 15 has'fan inwardly pro jectihg lug 18 at its rear end, said 1u being triangular, with its apexengagingt e rear portion of the jaw member 16, The nur.-`

pose of this lugis lto 4enable theA jaw 1'5 to be tilted `with respect to the jaw 16 as shown dotted in .Fig '3, so that Athe clamp canbe made tofit a Windshield frame of almost any shape or size.A In orderrtliat the jaw 15 may` be tiltedvas described,.the.bo1t holes through ivhich the bolts 17 pass'faxjeenlarged" sutiicently to. tallow the necessary playa.

The shankuof the jaw qlmis formedwith 'i a circular, disk-like enlargement 19 and a threaded Stem 20 extending rearv?ardlyv therefrom. This stemvsupports a bracket arln 21 having a disk-like enlargement-'221% its inner end, provided with ay perforation* at the center so that it may be slipped over` the stem, on which' latterit is secured by atill i nut 23. The parts 19 and Q2 "are c*:lampedf'` together bythe nut', andjn odert obtain; a better hold, the ,contiguousfaces'thereof,

The' inner end of the 'signal arln shank 7 also has` a circular head or eiilargexnent 26 through 4which the bolt 25 passes. Under the head 2T of the bolt 25 is held a clip 28 for supportir'ig the wiring 1t). The bolt projects from the part 24;, and on its project-ing -end threaded anni4 29, with a spring 30 coiled around the projecting bolt end, between the part 24 and the nut, whereby the parts 24 and QG are yieldably clamped together. The shank 7 is adjustable 'to Set the signal arln 5 straight ahead or pointing sidewise to the ri ghi'. or the lett, and in order to hold the shank in these three positions, the face of the part* 26 which engages the part 24 has :1 lug 31 en tering and Seating' in notches in the latter part'- these notches correspondinllr in inn-n* ber and position to the dilferent por-.itions the, shank may be set.. rl`he spring itl has sufficient tension on the pivot joint to hold the Shank in the position it may he set. its normal position being straight alie-ach and when it is swung to point to either side7 the lug 3l slips out of the notch .in which' it was seating 1fA` andwhen the shank arrives in the desired position, the lug slips in the proper notch. The necessary lateral movement of the part 'with'respect to the part 24 for permitting the hereinbefore described action the lug 3l is obtained by having the bolt 25 passing loosely through the part 24.

. To facilitate the control of the signal arm 5, lthe part 26:' has a projecting actuating arm 32.

- To the part`22 is anchored one end of a tension spring 33 having its'other end connected tothe part 26. This spring is ar ranged radially with respect to the pivot-al axis o1 the part L6, and it is pnt under tension when the latter is rotated to bring tho arm 5 into the side display positions as shown dotted in Fig. 1. A slight jar will disengage the lug 31, whereupon the spring 33 will bring the arm ing a corner to theleft, the signal arm will be thrown to'point to the left and'it remains longenough .inrthis position to warn. any approaching vehicle. When aturn to the right made, the signal arm will be thrown to point sidewise to the rightto warn pedes trians or ears approaching' from infront.

5 back to straight. When tuur' The normal position of the. signal arm is straight ahead, in which position it remains as long as the car is going straight ahead.

0n the parts 24 and 32 are cooperating stops tif-L and 35, respectively, by which the maximum throw of the signal arm is controlled. These stops also prevent the signal arm from colliding with the windshield o being thrown to the right. There are two stops 34 although one only is shown in Fig. '1, the position of the other one being covered by the wire 10.

It, will be noted that the inner end ot the shank 7 extends laterally with respect to 'the arm 5, this lateral portion being of such length that the arm clears the i-vindshield and comes in front thereof when it is swung over to point to the right shown dott-ed in Fig. l. The spring 33 is anchored to the laterally extending inner portion of the shank 7, and hence 1t is placed under tension when the arm 5 is swung in either direction to display position.

claim: A

1. A vehicle direction signal comprising a signal arm normally pointing in a certain direction, a shank' carrying the arm and having a laterally ,extending inner end which is pivotally supported to permit the arm to he swung to point sidewise in either direction from its normal position, and a tension mein-ber connected to the laterally extending ortion of the shank .and arranged radially .with respect to its pivot, said member being placed under vtension sidewise position to restore the arm to normal position. y

2. A vehicledireetioh signal comprising. a signal arm mounted at the Side of the vehicle and normally pointing straight ahead.y lsaid arm being:` pivotaflly supported to Swing' in ahoriZont-al plane for adjustment to'point laterali "to either side, and a ,tension member connted to th signal arm and arranged .radially with respectl to its pivot, and tending to restore the arm to the first-mentioned position, said member .being placed under tension when the arm is swung to point in the other directions.

In testimony whereofl affix my signature.
